The compositions of the present invention may be diluted by the user prior to use or used directly. The preparation can be prepared by common processing method, namely, mixing the active substance with liquid solvent or solid carrier, and adding one or more surfactants such as dispersing agent, stabilizer, wetting agent, adhesive, defoamer, etc.
The specific preparation of the weeding composition is dispersible oil suspending agent, water suspending agent, suspending emulsion, wettable powder, emulsifiable concentrate, water dispersible granule (dry suspending agent), water emulsion and microemulsion.
Briefly, the compositions of the present invention can be mixed with solid and liquid additives conventionally used in prior art formulations. The amount of the active ingredient used varies with the external conditions such as temperature, humidity, the nature of the herbicide used, and the like. It may have a large variation, for example between 0.001 and 1.0kg/ha, or more, of active substance, but preferably between 0.005 and 750g/ha, in particular between 0.005 and 500 g/ha.
In addition, the compositions of the invention can be applied by spraying onto the foliage of the plants to be treated, i.e. onto weeds, in particular onto surfaces which are infested or susceptible to infestation by weeds.
Further, the invention also provides application of the weeding composition in weed control; and a method of controlling unwanted plant growth comprising applying the herbicidal composition to plants, plant parts, plant seeds or areas of plant growth. Preferably, the herbicidal composition is used to selectively control weeds in crops of useful plants, more preferably in crops of useful plants which have been treated by transgenic or genome editing techniques.
The compounds of the invention are useful for treating all plants and plant parts. Plant varieties and cultivars can be obtained by conventional breeding and breeding methods or by genetic engineering methods. Genetically modified plants (transgenic plants) are those in which a heterologous gene (transgene) has been stably integrated into the genome of the plant. The transgene defined by its specific location in the plant genome is referred to as a transformation event or transgenic event.
Genetically modified plant cultivars that can be treated according to the invention include those that are resistant to one or more biotic stresses (pests such as nematode animals, insects, mites, fungi, etc.) or abiotic stresses (drought, low temperature, soil salinization, etc.), or which contain other desirable characteristics. Plants can be genetically modified to exhibit traits such as herbicide tolerance, insect tolerance, modified oil characteristics, or drought tolerance. Information on available genetically modified plants comprising a single gene transformation event or a combination of transformation events can be obtained from publicly available databases maintained, for example, by the U.S. department of agriculture.
When the herbicidal composition of the present invention is applied, its herbicidal activity achieves unexpected synergistic effects with respect to a single agent and any binary composition therein. The synergistic effect is manifested by a reduced application rate, a broader weed control spectrum, a faster and more durable herbicidal action, which are desirable in the practice of weed control. These new compositions are significantly superior to existing herbicides in terms of the characteristics described, achieving reduced use and being more environmentally friendly.
The synergistic weeding composition provided by the invention also has the following advantages:
(1) The composition of the invention is environment-friendly and is easy to degrade in the environment.
(2) The weeding composition disclosed by the invention is low in cost and convenient to use, and has great economic and social benefits in popularization and application.

The raw materials are all diluted by using acetone as solvent and 0.1% of emulsifier Tween-80 aqueous solution, and the diluted materials are diluted at present.
2.2 Test treatment
2.2.1 Dose setting)
In determining the ratio or content of component A and active ingredient B, C, the main purpose of the formulation should be considered in consideration of the characteristics of the drug and its toxicity. The study was based on the preliminary pre-test, and the single use and the mixed use of A, B, C active ingredients are shown in the table. Water without agent, with the same solvent and emulsifier was used as a blank.
2.2.2 Test repetition
Each treatment was repeated 4 times, 3 pots each time, each pot was sown with 30 weed seeds.
3) Test method (soil sealing treatment):
Irrigation was carried out before treatment, and a 1-2cm aqueous layer was maintained. Taking quantitative liquid medicine by a liquid shifter, and respectively irrigating from low dose to high dose according to test design, wherein each treatment is repeated for 4 times; after treatment, the cells were transferred to a greenhouse for routine cultivation, and a 1-2cm aqueous layer was maintained throughout the test period.
4) Data investigation and statistical analysis
4.1 Investigation method)
The entire seedlings of surviving weeds were cut off along the soil surface with a blade by an absolute number survey method, and the fresh weight of weeds was weighed with an analytical balance. For weeds that have died, the fresh weight is zero.
4.2 Time and number of surveys
The investigation was performed 15 days after the treatment, 1 total time.
4.3 Data statistics analysis
And (3) evaluating the combined action type of any two and three mixed weeds by using a Colby method.
And (5) shearing green tissues on each treatment ground at 15d, weighing by adopting an electronic balance, and calculating the actual survival rate: e (%) = (fresh weed weight in treated area/fresh weed weight in control area) ×100
The theoretical weed survival rate calculation formula is: e0 (%) =x×y/100 (binary mixture)
Wherein X represents the survival rate of A at P, Y represents the survival rate of B at Q, E0 represents the theoretical survival rate of A+B at (P+Q), and E represents the actual survival rate of each treatment.
E0 (%) =x×y×z× … ×n/100 (n-1) (ternary or higher mixture)
Wherein X, Y, Z, N respectively represent the actual survival rate of n single agents, and n is the number of the compound herbicide varieties.
When E0-E >10%, it is shown that a synergistic effect is produced; antagonism is indicated when E0-E < -10%; when E0-E is between.+ -. 10%, this indicates that an additive effect is produced.
The actual control of the individual components on weeds and the statistical results of the combined action evaluation are shown in tables 1 to 12 below.

C) Demonstration of field
The herbicidal compositions prepared in examples 1 to 12 were used for field weed effect tests. Weeds occurring in the field are mainly: barnyard grass, indian arrowhead, rhizoma alismatis, long-term rain flower, festival dish, fluorescent rush, special-shaped nutgrass flatsedge, cyperus rotundus and the like.
The test method comprises the following steps: after the rice is transplanted for 5-7 days, the rice field is irrigated and leveled, the liquid medicine is evenly mixed with water of 45L/ha and is evenly thrown and applied to the rice field with a water layer of 3-7 cm, the water is not discharged within 2 days after the application of the liquid medicine, and the water layer of 3-4 cm is maintained for more than 10 days. The specific test agents and dosages are shown in Table 13. The effect of controlling and preventing was examined 45 days after the application and is shown in Table 13.
Exemplary field effects of the formulated compositions described in Table 13
Through a large number of experiments and researches, the composition is unexpectedly found that the composition has a surprising and unexpected synergistic effect when used for preventing and killing various gramineae, broadleaf weeds, cyperaceae weeds and the like in a transplanted paddy field, the synergistic effect is more remarkable under a low dosage, the duration of the synergistic effect is longer than 45 days, and the purposes of one-time use, one-season weed-free, time saving and labor saving are achieved. And has high efficiency on ALS and ACCase inhibitor resistant weeds and good application prospect. Meanwhile, the herbicide composition shows good selectivity and excellent synergistic effect in fields such as direct-seeding rice, capsicum, eggplant, tomato, potato and the like through tests, and can be developed into herbicide mixtures with wide market value.
